Use This sensor is only to be used for the intended purpose and under safe conditions. Improper use or misuse can be dangerous. CAUTION Since these sensors are made of glass, they should be handled with care. Take care that the PG13.5 thread and the O-ring are not damaged while the sensor is installed into the adapter etc. 6.1 Preparing Carefully remove the storage cap by turning a screw located at a blue gasket. Rinse the sensor with water. Check the interior of the ph glass membrane for air bubbles. Allow any bubbles to rise to the top by shaking the sensor gently. PH4FE sensor: Prior to measuring, open the reservoir stopper; close it after measuring. Check level of electrolyte in the sensor. 6.2 Electrical wiring The sensors are equipped with a S8, S7 or a VP connector head. Before connecting the sensor to the cable, check that the connections are clean and dry. Do not touch the electrical contacts! Connectors especially should not be disconnected in moisture condensing environments. Unstable signals, low slope or long response time could indicate a moist or contaminated connector. Clean the connector head with a paper towel moistened with ethanol. Dry the connector head after this procedure with a dry paper towel. Attaching/detaching method of sensor cable In case of VP connector Rotating the sensor connector so that its recessed portions will agree with the salient portions inside the cable connector, insert the sensor connector into the cable connector. A weak pressure is sufficient for inserting it. If a strong pressure is needed to insert it, the connection position will be incorrect. Check the position and re-try.

20 After inserting the sensor connector completely, grip the portion A, and rotate the cap nut ( B portion) clockwise until the nut cannot rotate. Gripping the portion A, and rotate the cap nut ( B portion) un-clockwise. After loosing the nut completely, grip and pull the plastic portion of the sensor from the cable connector. CAUTION Do not grip or rotate the glass body of the sensor, but the plastic body of the connector. If the glass body is gripped, the sensor may be broken. 13 A B A Recess for positioning the sensor and cable B TIIS explosion-proof Tag (Attached only to PH4 T, but valid only in Japan) (Sensor side) (Sensor side) Attaching/detaching NOTE TIIS explosion approval is valid only in Japan, hence users remove TIIS explosion-proof tag and may use PH4 T in hazardous area, or non-hazardous area except Japan. NOTE If conduit is used, the metal part of the cable connector should not be in contact with metal parts of the conduit. If the metal part of the cable connector is in contact with other metal parts, this may cause measurement errors. 6.3 Procedure for Assembling of Sensor into Holder Install a sensor where a cable is connected according to 6.2 in a holder, when a holder is used. For use of the model PH8HF flow-through holder (1) Remove the nut for fixing the sensor to the adapter. (2) Pass the cable through the nut. (3) Attach the O-ring attached inside the holder, to the adapter. (Refer to the O-ring position in below figure.) (4) Put the sensor into the holder, and fix the adapter by screwing the nut.

21 14 For use of the model PH8HS submersion holder (1) Remove the protector and piece of foam rubber. This rubber is for transportation. (2) Pass the O-ring through the cable, and mount it to the upper side of the adapter. (Refer to the O-ring position in below figure.) (3) Pass the cable through the holder from the protector attachment side, and fix the sensor by the protector. (4) Fix the sensor cable to the holder. Thread for attaching to the sensor O-Ring position for using the PH8HS holder Adapter O-Ring position for using the PH8HF holder 6.4 Storage Sensors should be stored with the storage cap attached, containing 1.5 to 2 ml of 3.3 mol/l KCl solution. Sensors stored dry exhibit temporary drifting values. If the sensor dries out inadvertently, it can be placed in 3.3 mol/l KCl solution, or ph standard buffer solution overnight to regenerate. 6.5 Regenerating Entire regenerating is not always guarantee. ph: Immerse sensor for 10 min in 0.1 1M NaOH, then for 10 min in 0.1 1M HCl. After regeneration, place the sensor in 3.3 mol/l KCl solution for a further min. ORP: Metal surfaces can be cleaned with slightly abrasive substances, such as toothpaste or very fine scouring powder. 6.6 General The life cycle of sensors is determined by requirements regarding response time, zero point and slope. Some of harsh measurement conditions might shorten life cycle. There is also a slight ageing factor during storage, therefore avoid a long period of storage. Use within a year is recommended. O-rings are subject to wear and tear and should be replaced regularly, at least once per year. Refer to spare parts regarding the parts number of O-rings. For Models PH4C, PH4CT, OR4C The new sensor is pre-pressurized at about 250 kpa. This pressure, after one year, at the liquid junction, will decrease to about half at normal ambient temperatures and atmospheric pressure. Taking this decrease into account, use the sensor. If the pressure of a sample solution becomes higher than the inner pressure of the sensor, the solution will permeate gel electrolyte in the sensor. As a result, the sensor can become unusable. A rough change of the sensor inner pressure can be known by the air layer length of a narrow tube in the sensor. The higher the internal pressure, the shorter the air layer. For sensors with temperature sensor, RTD (Models PH4PT, PH4FT, PH4CT) Sensors with a VP type connection have a built-in temperature sensor (Pt1000). This temperature sensor is to be used only to compensate the ph signal and not to control process temperature.
